REPLACING-FROG FOR CARS OR LOCOIVIQTIVES.

SPECIFICATION forming part of Letters Patent No. 632,476, dated September 5, 1899.

Application filed September 24, 1896. derial No. 606,807. (No model- To all whom it may conccrn Be it known that I, BURT E. TILDEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway Replacing-Frogs; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

The present invention relates to that type of portable frogs employed in replacing derailed locomotives, cars, &c., upon the track, and has more especial relation to the type of such frogs that constitutes the subject-matter of my former Letters Patent, No. 388,779, dated May 29, 1888, the object of the present improvement being to provide, in connection with such hollow type of replacing-frogs, a simple and effective toggle clamp or tie that is adapted to afford a strong and durable connection and which is capable of easy application and detachment in comparatively inaccessible positions-as, for instance, beneath the fire-box of a derailed locomotive. I attain such object by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a transverse sectional elevation illustrating the present invention in place upon a railway-track; Fig. 2, a plan view of the same; Fig. 3, an enlarged detail elevation of the toggle-clamp of the present invention; Fig. 4, a transverse sectional elevation.

Similar letters of reference indicate like parts in the several views.

Referring to the drawings, A represents the rails of a railway-track, and B the portable replacing-frogs, that are adapted to have substantial attachment to the trackrrails A when employed in replacing a derailed train of cars, doc. Each replacing-frog B will be of the same general form and construction shown in my former patent and formed with inner and outer vertical walls, an open bottom, and a segmental top wall that inclines downwardly toward the adjacent rail,as shown,and as fully set forth in my aforesaid prior patent.

C are the attaching toggle-clamps by which the respective replacing-frogs are attached to the respective track-rails. In the presentimprovernent each of said attaching-clamps is formed at one end with a hook-shaped jaw D, adapted to engage the base portion of the rails A, and at the other end with an angular flange or jaw E, adapted to engage the wall of the hollow frog next adjacent to the rail, and in some cases said flange formation E may be provided with an adjustable abutment or setscrew F to constitute an adjustable bearing at such point to enable the replacing-frog to be used in connection with rails having bases of difierent widths, as well as to permit of the frog being placed in a slightly-oblique position in a horizontal plane with relation to the rail, so as to afford a broader scope to the frog in taking up a derailed wheel. When such oblique adjustment is desired, the set-screw F will be unscrewed to permit of such oblique adjustment of the required end of the frog, after which a wedge, boulder, or other convenient article is forced between the separated and adjacent faces of the frog and of the rail to cause a rigid connection of the frog in place.

It is a material portion of the present invention to make the engagement between the frog B and the toggle-clamp C by means of the nearest vertical wall of said frog in that the clamp can be made of a very short and compact nature,so as to aiford a maximum amount of strength and rigidity in use, and while affording a very substantial attachment for the frog at the same time permit of a ready and convenient subsequent disengagement when required, and what is of still greater practical moment to require but a minimum amount of excavation of the roadway metal or ballast in applying the frog to the track for use in replacing a locomotive, car, 850.

Another feature of the present improvement consists in forming the main body portion of the toggle-clamp C of a downwardlybent nature toward the flange formation E thereof and as shown in Fig. 4E. WVith this construction the lower face of the frog can be forced down into the roadway by undue and excessive weight without coming in contact with such body portion of the clamp to strain its connection to the rail, or, on the other hand, spring or bend the rail out of proper line.

In practice, when a car or locomotive is to be replaced, the toggle-clamps are hooked under the rails, as shown, and the replacing-frogs engaged by means of their adjacent vertical walls with the flange formations of the clamps, after which by a light blow the frogs are forced longitudinally to cause the clamps to assume an oblique position and firmly clamp the frogs in place ready for use in replacing a car, &c. A subsequent disengagement of the frog is effected by a light blow in an opposite direction to that given in effecting the engagement thereof with the rail. 1

The described construction and operation of the present toggle-clamp affords a very convenient means for attaching the frogs to the rails in comparativelyinaccessible positionssuch, for instance, as beneath the firebox of a derailed locomotive. In such circumstance an engagement or disengagement can be Very conveniently effected with the present construction and which would be well nigh impossible with the screw-clamps of pre viously-proposed replacing-frogs.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a hollow replacingfrog having an inner vertical wall next adjacent the rail, and a toggle clamp or tie formed with engaging jaws at each end that engage the inner vertical wall of the frog and the base of the rail, and is adapted to effect a rigid engagement of the parts by a toggle or oblique movement substantially as set forth.

2. The combination of a hollow replacingfrog having an inner vertical wall next adjacent the rail, and a transversely-inclined segmental top, and a centrally-arranged toggle clamp or tie formed with engaging jaws at each end to engage the inner vertical wall of the frog and the base of the rail, and is adapted to effect a rigid engagement of the parts by a toggle or oblique movement, substantially as set forth.

3. The combination of a hollow replacingfrog formed with an inner wall next adjacent the rail, and a clamp adapted to have engagement with said wall, and the base of the rail, said clamp being formed with a downwardly-bent body portion, substantially as set forth.
